Project Earth (TV Series)

Project Earth is a recent reality TV series on the Discovery Channel
in which several groups of scientists experiment with radical ideas to slow and/or stop global warming with the financial aid of the Discovery Channel.

experiment. Their goal was to make clouds more reflective to bounce more of the Sun's heat generating rays back into space as a stop-gap against global warming. By changing the size of water droplets within a cloud, they make clouds brighter and reflect the sun's heat into space. They choose to seed marine stratocumulus cloud

to form droplet particles that are one micrometre in diameter, and that can rise to 300 ft (91 m), even in adverse (cloudless) conditions. The experiment proves that man-made droplets can indeed seed stratocumulus clouds.

After a series of computer simulations based on current and rising CO2 levels, Basil determined that without the proposed fleet of ships, the average global temperature would rise 2.9 degrees Celsius by the end of the 21st Century; enough to melt glaciers that are important to the freshwater needs of Asia and Africa and the hydro-electric power needs of Europe. Using a fleet of 1500 cloud enhancing ships employing the recently discovered technologies would reduce that average global temperature change to only 1 degree Celsius by the end of the 21st century. The slower rise in temperature would grant humanity more time to reduce carbon emissions before a major climate related catastrophe was likely to strike.
The estimated cost of the fleet of remote-operated cloud enhancing vessels would was valued at $5.8 billion US, a fraction of the $44 trillion US world economy

in which several groups of scientists experiment with radical ideas to slow and/or stop global warming with the financial aid of the Discovery Channel.
Projects
The show consists of eight experiments to weigh pros and cons of ideas on how to reduce global warming. The projects are as follows:Wrapping Greenland
Seeing if glacier melting can be prevented by wrapping them in blankets. LRaining Forests
Led by scientist Mark Hodges, they attempt to reforest areas of bare Earth from helicopters using canisters holding a tree seedling.Brighter Earth

Cloud reflectivity enhancement
Cloud reflectivity enhancement is also known as 'marine cloud brightening' or 'cloud whitening' on low cloud. An opposite scheme exists to reduce the reflectivity of higher, colder cirrus clouds. It is a geoengineering technique that works by solar radiation management. By modifying the...

Stratocumulus cloud
A Stratocumulus cloud belongs to a class of clouds characterized by large dark, rounded masses, usually in groups, lines, or waves, the individual elements being larger than those in altocumuli, and the whole being at a lower altitude, usually below 2,400 m...

The world economy, or global economy, generally refers to the economy, which is based on economies of all of the world's countries, national economies. Also global economy can be seen as the economy of global society and national economies – as economies of local societies, making the global one....

Infinite Winds
Testing of a revolutionary wind turbine led by engineer Fred Ferguson in an attempt to harness the energy of high-altitude winds. The team will test a 70 feet (21.3 m) prototype attached to a blimp over The Appalachians to harness the endless supply of wind.Hungry Oceans
Dr. Brian von Herzen and the Discovery team join Professors David M Karl (University of Hawaii) and Ricardo M Letelier (Oregon State University) to test wave powered pumps in an effort to bring nutrients from the depths of the oceans to the surface. This nutrient enrichment of the open ocean's well-lit surface layers is needed to enhance photosynthesisPhotosynthesis
Photosynthesis is a chemical process that converts carbon dioxide into organic compounds, especially sugars, using the energy from sunlight. Photosynthesis occurs in plants, algae, and many species of bacteria, but not in archaea. Photosynthetic organisms are called photoautotrophs, since they can...

Phytoplankton
Phytoplankton are the autotrophic component of the plankton community. The name comes from the Greek words φυτόν , meaning "plant", and πλαγκτός , meaning "wanderer" or "drifter". Most phytoplankton are too small to be individually seen with the unaided eye...

Attempting to create a 100000 square miles (258,998.8 km²) sunshade by placing trillions of lenses in space, led by astronomer and professor Roger Angel. Angel has developed a diffraction pattern by etching onto a lens, which will deflect the sun's rays.Orbital Power Plant
Former NASA physicist John Mankins's vision of launching thousands of satellites into space, gathering solar energy from the sun and beaming it down to Earth as microwave energy. The energy will then be collected by antennas on the ground, which will convert it into electricity.Fixing Carbon
